eSIM Travel Tips for Las Vegas

Sort your eSIM before you leave Dublin
Buy your HelloRoam eSIM for Las Vegas at home, scan the QR code over Wi-Fi, and switch on data when you land at Harry Reid International Airport. You step off the plane already connected on local 4G LTE. No queuing at airport telecom shops.
Keep your Irish number live
On a dual-SIM phone, leave your Three Ireland, Vodafone Ireland, Eir, or GoMo SIM active for calls and texts. Use HelloRoam for data in Las Vegas. People back home can still ring your Irish number without international charges.
Download offline maps first
Save Google Maps or Maps.me for Las Vegas offline before you fly. Offline navigation uses no data and keeps working even where signal is patchy. It's a handy backup when you arrive and need directions quickly.
Watch your data usage
The HelloRoam app shows your balance in real time. You get alerts at 80% and 95% usage so there are no nasty surprises. Top up inside the app if you need more data in Las Vegas, no reinstall needed.
Save emergency numbers offline
The emergency number in most countries is 112. In Las Vegas it is worth checking the local number too. Save these offline before you travel. Emergency calls work on any available network regardless of your HelloRoam data balance.
